工业纯钛TA2室温蠕变第1阶段特性研究 王志文1,徐宏1,张莉1,马秋林1 (1.华东理工大学,上海,200237;2.杨子石油化工股份有限公司,江苏,南京,210048) 摘要:研究了工业纯钛TA2室温下蠕变第1阶段的特性.结果表明,TA2材料室温下确实存在明显的蠕变现象,并且存在一个临界应力值,低于该临界值的TA2在室温下不会发生蠕变.TA2室温下蠕变第1阶段的规律为β蠕变.针对TA2材料室温下第1阶段的蠕变特性,本研究提出了一种新的β值与应力间的关系表达式:β=β0(σ-σc)m,其中σc为蠕变临界应力.并且得到室温下TA2的蠕变临界应力值为267.25 MPa. 关键词:工业纯钛TA2; 蠕变第1阶段; β蠕变; 蠕变临界应力; [全文内容正在添加中] ......
