According to this study, it is estimated that the ILDU historic house was constructed around the late Goryeo period, approximately in the year 1360, and the founder moved to Hamyang no earlier than 1350. The main house, the inner store-house, the inner gatehouse, and the ancestral shrine, which are situated on elevated ground, were initially constructed around 1360, and substantial expansions and renovations occurred around 1620. The shrine was relocated and reconstructed in its present location and form around 1843. Subsequent to that period, it underwent various architectural changes, including repairs and reconstructions. The sub-main house was originally constructed around 1620 and underwent a reconstruction in 1843. The main storehouse was built in 1930. Also, the man’s part of house, located on lower ground, was erected in 1843, while the other sub-main house seems to constructed around 1860. The auxiliary buildings, the main gatehouse and the outer storehouse, were initially constructed around 1360. It is estimated that they were similarly relocated and reconstructed in their current form, along with the construction of the man’s part of house in 1843. It has undergone a four-stage transformation process, influenced by various internal and external factors, including the local indigenization of the ILDU families of the same clan, as well as the popularization of Confucian ideology. These four stages include its formative period, growth phase, developmental stage, and maturity. It actively incorporated the contemporary factors of change into its residential architecture. This continuous adaptation is evident in its the space and floor plan, ultimately leading to its present-day architectural legacy.

The tensile strength of the grain coarsened HAZ was always higher than that of base metal, but yield strength was lower than that of base metal at cooling rates, t_8/5>60. The strain hardening exponent, n, is reduced with increasing cooling rates and this is due to formation of martensite with high dislocation density. In slower cooling rates, the formation of ferrite side plates gives rise to a substantial increase in the strian hardenability.

Cu-Zn-Al형상기억합금의 파괴 특성

정인상,박경채 慶北大學校 1986 論文集 Vol.42 No.-

This study is aimed to clarify the fracture mechanism of Cu-Zn-Al shape memory alloys which are known to have better mechanical properties than other Cu-base alloys. The results obtained are as follows; Fracture stress and fracture strain shows different values with different composition, but in the three deformation mode (deformation in martensite, pseudoelastic deformation of the matrix, and deformation of matrix where SIM does not occur) stress-stain curves are similar each other. And during the pseudoelastic deformation fracture occurs most easily. Fracture in martensite depends on the easiness of martensite varients movement of reorientation. In the case of large grain size, grain constraint effect decreases and movement or reorientation of martensite varients are very easy. In the case of small grain size, on the other hand, movement or reorientation of martensite varients are very difficult and cracks initiate at the three-fold node of grain boundaries. In the case of pseudoelastic deformation of matrix state, different of maximum recovery strain causes stress concentration at grain boundary and cracks initiate at the three fold node of grain boundaries. If crack grows long enough, a stress concentrates at the grain boundary. So with increasing grain size or decreasing thickness of specimen, fracture occurs more easily. And in the case of matrix state which SIM can not be made, fracture occurs along the grain boundaries within elastic deformation owing to elastic anisotropy. But if the plastic deformation like ship occurs, stress concentration of grain boundaries can be relaxed easily.

The shape recovery behavior in Ni-A1 base shape memory alloy whose ductility is improved with Fe and Mn alloying has been investigated by using DSC, XRD and TEM. On heating, the deformed alloys were experienced a double-stage recovery process before they returned to the original shape : The first-stage recovery occurred at lower temperature and the second-stage recovery take place at higher temperature. Increase of bending or tensile strain affected total shape recovery such that it leaded to an increase of the second-stage shape recovery. The shape re-covery at a higher temperature, i.e., second-stage shape recovery was attributed to the hinderance of β' →β transformation by the dislocations in β' martensite introduced during deformation. Possibly, the elastics stress field associated with dislocations would hinder the motion of β'/β boundary. When the alloys were bended at the same strain the second shape recovery increased with annealing at higher temperature because of the increase of volume fraction of the β' martensite in the alloys consisted of β' martensite and β phase.

In Cu-Tn-Al shape memery alloys, it is necessary for practical application that mechanical properties of the alloys is modified by grain refinement. In present work, grain was refined by adding misch metal, Mn or Ni and mechanical and thermal cycling test have been done. In the case of Mn and Ni effect of grain refinement were small. It was, however, predominated by a factor of 20 in the case of misch metal. The fracture stress and the strain of the refined alloy with size of 50㎛ were increased with 2 and 1.3 times than those of the alloy not to be refined, respectively. Shape memory effect was not affected significantly by decreasing grain size, but fatigue life by thermal cycling in the refined alloy was increased with 1.5 times.

Effects of cooling rate, quenching temperature and holding time on the morphology and the composition of the precipitates at the prior austenite grain boundary were investigated in boron steel. Morphology of the precipitate was plate type and independent of quenching temperature and holding time. But the increase in the cooling rate decreases the thickness and length of the precipitates. The precipitate at the prior austenite grain boundary was Fe₃(CB) and independent of cooling rate, quenching temperature and holding time. Boron content in Fe₃(CB) was 7.5at% at 20℃/sec and 11.0 at% at 1℃/ sec.
