Investigation of dissolution resistance of blank and gas-nitrided carbon steels in stationary SAC305 solder alloy melt by Benke M., Salyi Zs., Kaptay G.

“…The objective of the present study is to investigate the suitability of a series of gas-nitrided steels with varying C content as candidates for wettable selective soldering tool materials with enhanced lifetime. ɛ and γ’ iron-nitrides were formed by gas nitriding on quenched and tempered DC04, C45, CK60 and S103 type steels. Contact angle measurements revealed that all four nitrided steels exhibit good wetting with SAC305 solder melt. …”

Study on Creep Characteristics and Constitutive Relation of Fractured Rock Mass by Maotong Li, Kesheng Li, Deng Zhang, Chuanxiao Liu, Depeng Ma

“…In order to effectively describe the whole creep process of fractured rock mass, triaxial unloading creep tests were carried out on prefractured coal samples using constant axial pressure and graded unloading confining pressure, and the axial and lateral creep laws of fractured coal samples with different dip angles were studied. Combined with the characteristics of creep curve and based on Kachanov’s creep damage theory, the damage variable is introduced into the constitutive relation and creep equation, and the evolution equation of damage variable with time in the whole creep process is derived. …”
