DBTT(Ductile-to-Brittle Transition Temperature,韧脆转变温度)是衡量材料(尤其是难熔金属)在低温下从延展性向脆性转变的关键温度指标。其数值受材料成分、加工工艺等因素影响,通过优化合金设计或改进加工方法可有效降低DBTT,从而提升材料在低温环境下的可靠性。 核心影响因素 材料纯度与合金成分:高纯度...

A dynamic small punch test technique is demonstrated for measuring the ductile-brittle transition temperature (DBTT) of aged Cr-Mo-V turbine rotor steels. Based on fracture energy measurements and fracture surface observations it is shown that the dynamic small punch test specimens exhibit a clear ...
如果拆开,有dbt+t,db+tt,d+btt三种拆法,会出现N多种可能。所以,你还需要根据谈论的事情,上下文的意思,去判断到底是什么意思。如果我遇到这种情况,会直接问:dbtt什么意思?dbt=代表团 大兵团 打不通 大白天 大半天 大白兔 大不同 大变态 道不同 等半天 大班台 对比图 点播台 蛋白糖 ...
