High - temperature dislocation creep in ni2geo4 spinel 镍锗尖晶石位错域的高温蠕变实验研究
Verification regulation of high - temperature creep and stress - rupture testing machine 高温蠕变持久强度试验机检定规程
Effect of rare earth modification and heat treatment on impact fatigue property of wear resistant white cast iron 50力学性能及高温蠕变的影响
Therefore , this thesis studied the creep properties of 2cr11nimovnbnb steel which is one of bolt material used in 300mw stream turbine 为此,本论文对国产300mw机组用于汽缸螺栓的2cr11nimovnbnb进行了高温蠕变试验研究。
Throughout the experiments , there is no accelerated creep regime , which is in accordance with most of the ceramic matrix composite 在实验过程当中没有观察到蠕变的加速阶段,这和大多数陶瓷基复合材料的高温蠕变现象是一致的。
The proper processing , which is difficult , can assure the final acceptable proportion microstructure ( fig . 1 ) and the expected high - temperature creep strength 正确的工艺过程(是很难实现的) ,可以保证最后能被接受的均衡微观结构和所期待的高温蠕变强度。
A suitable damage parameter is needed to fully describe the process . the variation of fractional electrical resistance increase and the variation of elastic module were adopted as damage parameter to identify the tendency of damage evolution 3d - c sic的高温蠕变过程也是其组织内部损伤不断演化的过程,选择合适的损伤变量可以很好地描述这个过程。
This kind of steel is a casting material of p91 , with the better performances of high temperature anti - oxidation , high - temperature creep rupture strength , t hermal conductivity and the lower performances of t hermal expansion . there is no casting in chinese 该钢种为p91对应的铸材牌号,材料具有良好的高温抗氧化性能,较高的高温蠕变强度、持久强度和韧性,低的热膨胀性,良好的导热性、加工性等特点。
The creep cavity location and damage of polycrystalline material was studied , and it was considered that there was a great correlation between the cavity sites , creep damage and grain size , and the damage often occurred in the location where grain size was small 摘要研究了多晶体材料在高温蠕变下的空洞出现位置和损伤特点,认为同一组织下空洞的出现及蠕变损伤的位置与晶粒尺寸有关系,晶粒尺寸小的部位易发生损伤。
