본 연구에서는 구리합금을 냉간 압연하여 이방성 재료를 만들었을 경우 재료 의 압연율과 열유동 방향의 변화에 따른 열확산 계수의 변화를 섬광법으로 측정하여 분석 하였다.
The variation of thermal diffusivity with respect to rolling reduction is experimentally determined by flash technique. Copper alloy is used as an experimental and specimens are cut from the slab produced by rolling process with different percent reduction in thickness along the rolling direction and with 30.deg. 60.deg. and 90.deg. angle to the rolling direction. It is found that thermal diffusivity is slightly decreased as rolling reduction increased, and it has tendency that thermal diffusivity is increased slightly as its angle approached to 90.deg. at same rolling reduction.
