; Abstract: The isothermal section at 927 ℃ of the Cr-Ni-Ti system was established using a high-efficiency diffusion couple approach, supplemented with eight equilibrated alloys...-Ni-Ti system is a subsystem in our research project[1-7] aiming at establishing a thermodynamic database for the C-Cr-Ni-Si-Ti quinary system. Ni-Cr based alloys are important corrosion-resistant......
in industry; confined to parts such as steering wheels, column supports, roof frames, and gear box housings. The highly essential and favored alloys currently in use are based on Mg-Al system...) The corrosion behavior of three cast and extruded Mg-alloys, based primarily on binary Mg-3Sn system with addition of Ca in the range of 1%-2%, have been investigated using polarization and salt spray......
; Abstract: The 5Cu40Zn55Al and 15Cu20Zn65Al alloys were prepared in the Al-Zn-Cu system. There exist the metastable phases ε and θ... As one of the most important systems in practical Al alloys, the phase diagram at room temperature in the Al-Zn-Cu system provides special reference for the natural or artificial aging of Al-based alloys......
升温过程中Nb和Nb-Mo微合金化钢中碳化物的析出行为研究张正延1,2,李昭东1,雍岐龙1,孙新军1,王振强3,王国栋21. 钢铁研究总院工程用钢研究所2. 东北大学轧制技术及连轧自动化国家重点实验室3. 首钢技术研究院摘 要:利用Gleeble热模拟实验机,Vickers硬度计,SEM,HRTEM及DSC研究了淬火态含Nb和Nb-Mo微合金钢在升温过程中碳化物的析出行为.利用经典形核长大理论及Avrami方程对淬火态钢中MC型碳化物的析出动力学进行了计算.结果表明,含Nb和Nb-Mo微合金钢淬火后以20℃/min的速率加热至不同温度水冷,在300和700℃,由于e-碳化物和MC型碳化物析出而出现了硬度峰值.MC型碳化物在650℃左右析出,由于析出强化而硬度上升,与理论计算得到的MC型碳化物的析出鼻子......

binary system had been assessed by adopting the ionic melt and the modified quasi-chemical models to describe the liquid phase with short range ordering behavior. In general considerations of the development of the thermodynamic database of the multi-component Mg-based alloys and the consistency of the thermodynamic models of the related phases, the Gibbs energy descriptions of all the phases......
