strain-hardening range 中文意思是什麼
strain-hardening range
解釋
應變硬化范圍-
It can be noticed that both r and t specimens show initial hardening and subsequent softening at the strain amplitude higher than 0. 8 % and cyclic softening from the beginning to fracture under strain amplitude less than 0. 8 % at room temperature, and the cyclic flow stress was always lower in r specimen than in t specimen at the same strain range
且在相同的應變幅下， t向試樣比r向試樣具有更高的循環流變應力。此外，對r向及t向試樣，低應變幅下呈現出循環軟化現象是因為晶粒旋轉導致循環軟化；而在高應變幅下發生循環硬化是由於孿晶作用的結果。 -
The alloys, which were cold - worked followed by recrystallization annealing, display cyclic softening in the range of low strain because the cyclic stress - strain curve lies below the monotonic stress - strain curve, and show cyclic hardening in the range of high strain because the cyclic stress - strain curve lies above the monotonic stress - strain curve
在低應變范圍，冷加工后經再結晶退火處理的錯合金的循環應力一應變曲線位於單調拉伸曲線的下方，表現為循環軟化;在高應變范圍則位於單調拉伸曲線的上方，表現為循環硬化。 -
For the cyclic deformation under a given strain at room temperature, cyclic softening is usually displayed till to failure in the lower range of strain ; however, cyclic hardening is displayed in the early stage in the higher range of strain, subsequent cyclic softening in the later stage and till to failure
對于室溫下恆應變幅的循環變形，在應變幅較低時表現為循環軟化直至疲勞破壞;在應變幅較高時，循環變形的初期為循環硬化，隨后是循環軟化直至疲勞破壞。
