Study on fatigue behavior in CuAlNi SMA wires with columnar grains casted by heated mold continuous casting process was carried on cyclic tensile testing at 4%, 6% and 8% strains.

用热型连铸法连铸了柱晶组织CuAlNi合金丝,在记忆状态下分别以4%,6%,8%应变量循环拉伸,以研究其疲劳性能。

Poly-Si thin films with columnar grains were fabricated by RTP using previous samples respectively deposited on glass and quartz substrates by RF-PECVD.

结果发现:(1)柱晶的形成对薄膜的厚度有一定要求,而且薄膜越厚,柱晶直径越容易长得更大。
