Ke-jun, ZHANG Zheng. Effect of tempering temperature on very high cycle fatigue behavior of 42CrMo steel[J]. Transactions of Materials and Heat Treatment, 2014, 35(S1): 175-180. [61] OGUMA H, NAKAMURA......
a composition of Al-4.57Cu-1.34Mg-0.81Mn (mass fraction, %). Prior to the hardening age, the alloy was solution heat-treated at 495 °C for 1 h and then water quenched to room temperature (20 °C... simulation of heat treatable aluminum alloys using differential scanning calorimetry [J]. Transactions of Nonferrous Metals Society of China, 2014, 24(7): 2157-2167. [54] GHEBOULI B, GHEBOULI M A, FATMI......
is widely used for the processing of specific industrial intermediates and materials and in the removal of undesirable scale and rust in metal working, such as cleaning of boilers, heat exchangers......
can be the large amount of heat energy generation, which would soften the underlying metal. If this happens, the upper oxide film weakly bonds to the un-oxidized bulk material at higher temperatures......
electrowinning [J]. Canadian Metallurgical Quarterly, 2009, 48: 326-337. [27] YAN Z W, MENG H M. Effect of heat treatment of titanium substrates on the properties of IrO2-Ta2O5 coated anodes [J]. Rare......
and there is no heat exchange with the outside world during the physical process. According to the First Law of thermodynamics: U=Ud+Ue  ......
molten aluminum. Further, the solidification rate is high at 630 °C due to low latent heat and high solid fraction. These two factors reduce the available time for the gas to escape, resulting......
and heat energy. The Qingshanjiao intrusion of Yanshanian is the primary factor for mineralization. Near the Qingshanjiao intrusion, the thickness of ore body increased, ore grade turned to be higher......
, and an electrochemically prepared sample as Cu-TESPA. The hydrolyzed Cu-TESPA without and with curing are recorded as Cu-TESPA-hydrolysis and Cu-TESPA- hydrolysis-heat, respectively. 2 Experimental 2.1... for 15 min under vacuum to produce Cu-TESPA-hydrolysis-heat substrate. The aim of using vacuum curing is to eliminate the effect of copper oxide probably obtained from atmosphere heating. 2.3......
; (9) where qmax and KL represent the maximum adsorption capacity for the solid phase loading and the energy constant related to the heat of adsorption respectively (Fig. 14). A plot of ρe/qe......
