hardness aging 中文意思是什麼
hardness aging
解釋
加工時效-
The time taken to reach maximum hardness decreased and the corresponding maximum hardness decreased with increasing aging temperature. the better properties of al - mg - si - mn - cr alloy were obtained after 8h at 175 ' c. the al - mg - si - mn - cr alloy resembles al - mg - si alloy in the way of the age hardening mechanism
在同一溫度下，隨著時效時間的延長，合金硬度逐漸上升，在達到時效硬度峰值后又逐漸降低，隨著時效溫度的升高，中南大學碩士學位論文川mg st mn cr合金組織與性能的研究合金達到時效硬度峰值的時間縮短，而相應的時效硬度峰值在減小。 -
Effect of different aging treatment on the hardness and wear - resistance of hardfacing layers
不同時效處理對堆焊層的硬度和耐磨性影響 -
Secondly, choose the sample component, as different particle match of tungsten carbide and specifically heat treatment craftworks of solution and aging manufacture test piece, watch metallurgical structure of the test piece and do the tests of hardness and tension, at last do the abrasive wear test on the dynamic load abrasive wear test machine, analyze test datum, from the test data, conclusions are arrived that the hardnees of composite - alloy can be improved and wear - resistance be better by adding cr and other elements according to a given ratio
本文對rp中速磨煤機耐磨件進行了運行與磨損情況分析，研究、提出了制備磨輥和盤瓦復合合金成分配比；並對製作的試件進行了固溶、時效等特定的熱處理工藝，觀察試件金相組織，進行機械強度試驗，最後做磨料磨損試驗，對磨損失效機理進行了深入的研究分析，對其耐磨性能與低合金鋼、高鉻鑄鐵進行了對比。 -
With the background of studying copper alloy bar for asynchronism traction electromotor, a kind of copper bar and its preparation techniques are developed, and its hardness, tensile properties, electrical properties and microstructure are studied. furthermore, the rule of structure and properties changing with heat - treatment is especially illustrated. the results show : the first, there is obvious aging strengthening effect in cu - 10zn - 0. 8 ( cr, zr ) alloy
