英文
granulation water temperature-
In this paper, 6013al / sicp / gr metal matrix composite ( mmc ) was produced by spray codeposition, by means of changing the medium of quenching, influence of five types of heat treatment system ( furnace cooling, air cooling, water quenching, dry ice quenching, liquid nitrogen quenching ) and different aging temperature on the damping was studied systematically
本文採用噴射共沉積方法制備了6013al sicp gr金屬基復合材料( mmc ) ,通過改變淬火介質,較為系統地研究了五種熱處理制度(爐冷、空冷、水冷、乾冰冷及液氮冷)以及不同時效溫度( 120 、 150 、 170 、 190及210 )對6013al sicp grmmc阻尼性能影響。The ceramic layer does not crack or flake off when heated to 800 and then quenched
將陶瓷內襯復合鋼管加熱至800高溫,然後水淬,陶瓷層不炸不裂。Over 310, liquid nitrogen quenching and water quenching show higher damping capacities
當溫度大於310 , - 195淬火與水淬試樣表現出較高的阻尼性能。But the activation energy of water quenching samples are very different at different aging temperature, the lowest is 1. 27ev and the highest is 2. 4 lev
而水淬試樣在不同的時效溫度下激活能計算的結果有很大的不同,激活能最低為1 . 27ev ,最高為2 . 4lev 。At the same time, water quenching at 190 aging exhibit the highest damping capacities. compared with furnace cooling which show the highest damping capacities in five heat treatments, it show higher damping capacities when tempera ture is under 120 and above 290. further more, it show constantly damping value ( tan above 0. 004 ), but the damping value of furnace cooling is just 0. 0015 under 75
水淬試樣在190的時效溫度下有最高的阻尼性能,通過與爐冷試樣的阻尼性能(五種熱處理制度爐冷試樣的阻尼性能較高)對比發現,在溫度低於120 、高於290范圍,水淬試樣在190時效溫度下的阻尼性能均高於爐冷試樣的阻尼性能,在120 290之間,它的阻尼性能低於爐冷試樣的阻尼性能,而此溫度區間正好是位錯內耗峰出現的溫度范圍。The lath width of martensite can be fined noticeably by pre - strained quenching at non - dynamic recrystallization to approach nanometer magnitude ( the average width is 120nm )
採用非動態再結晶溫度下的預應變-淬火,提高馬氏體相變形核率,可以超細化馬氏體的板條晶片寬度,使之接近納米量級水平(平均寬度達到120nm ) 。The extruded az91d alloy was heated continuously and soaked at constant temperature. then it was quenched in the water and the instant texture at high temperature was acquired
首先對經過擠壓形變的az91d鎂合金分別進行連續加熱及等溫保溫,然後水淬快速激冷固定其高溫瞬時組織。分享友人
