residual hardness 中文意思是什麼
residual hardness
解釋
殘余硬度-
Among these physical properties are appearance, wear resistance, hardness or brittleness, residual stress, porosity, thickness, and deposit uniformity.
這些物理性能有外觀，抗磨損性，硬度或脆性，殘余應力，孔率，厚度和沉積層的均勻度。 -
The multi - purpose tester developed here is aim at testing the mechanics performance of the brittle material, which bases on modular design thought, it contains several modules as the machinery load component, platform of supporting, the function modules and the software system, they can be combined in different function modules to satisfies the need of different application situation. the tester can be used to measure not only general material properties such as elastic modulus, ultimate strain, strength, hardness and toughness, fatigue properties but also various special properties such as the local strength, and surface residual stress at the different location of the brittle component with non - destructive methods. thus the security and reliability of the brittle component can be evaluated and predicted
本文基於模塊化設計思想，研製了一臺專門針對脆性材料力學性能測試的多功能脆性材料試驗儀，其主要包括機械加載模塊、支撐平臺、功能模塊、測控系統、軟體系統等模塊，通過對這些模塊的不同組合可實現不同的功能及滿足不同應用場合要求;系統除了具有測試脆性材料的彈性模量、極限應變、強度、硬度、韌性等常規性能外，還具有無損測試玻璃構件不同位置的局部強度和表面預應力，進而對玻璃構件的安全可靠性和壽命進行預測等功能。 -
And we also discovered there is no decreasing of the hardness on the surface of cr12 steel. it is due to dispersion harden by plentiful of alloy carbide and decreasing of residual austcnitc. these research work should provide some useful references for technicians in practice. at last, the program was also introduced
但在高合金鋼cr12中發現硬度回落現象並不明顯，這是因為本身該鋼種的激光加工硬化帶硬度並不大，另外高合金含量產生的彌散強化以及殘余奧氏體的減少也是硬度回落小的一個原因。 -
Are made of tempered martensite, with moderate hardness, excellent elasticity, wear - resistant, give less dust, longer recycle life, low cost, extensively used for shot peening to give residual stress in the surface layer of components for fatigue life enhancement and suppression of stress corrosion cracking and descaling and cleaning up surfaces of castings, steel parts and mechanical work - pieces prior coating
鋼丸鋼砂主要金相組織為?火馬氏體組成，具有適當的硬度良好的反彈性耐磨性粉塵少循環使用壽命長成本低等特點，廣泛應用於鑄件鋼件機加工件的表面噴塗前的表面去皮，清理。
