Various hydrogen contents in thee ingots were produced by maintaining the equilibrium on different pressures of hydrogen input in a vacuum induction furnace and the alloy melts before casting. The results show that no matter what the original hydrogen contents, e. g. 2.0 to 19.6 ml/100 g, of the ingots are, neither marked difference to the ductility between high and low hydrogen containing ingots nor low tensile ductility region under medium temperature is found if the ingots are dehydrogenated to such extent of similar hydrogen content about 0.5 ml/100 g.The influence of trace Pb on medium temperature tensile ductility of the alloy has also been studied. Serious ductility deterioration was found and low tensile ductility region under medium temperature was obtained when Pb exceeded 2 ppm. This harmfulness may be explained by the diminishment of the granular strength and the equi-strength temperature of GH132. 收稿日期: 1982-06-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 傅杰 徐志超 于永泗 赵文祥 高良 李顺来 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I6/651 1 长谷川太郎,日本金属学会志,24(1960) ,A28． 2 川畑正夫,铁钢,47(1961) ,604． 3 北京钢铁学院高温合金教研室,GH 132合金,国防工业出版社,1980,p.87． 4 Gao, L.; Fu, J.; Chert, C.
