Study on aging strengthening and nano precipitates of Cu–Ni–Mn–Fe alloy

Materials Research Express (2020)

Juntao Zou Lin Shi Hao Shi Qiaoli Feng Shuhua Liang

Abstract This paper presents a systematic study of the precipitation strengthening mechanism in polybasic Cu–Ni–Mn–Fe alloy. The effect of aging treatment on the microstructure, morphologies and phase transition of the Cu–Ni–Mn–Fe alloy were analyzed and discussed using scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) and differential scanning calorimeter (DSC), respectively. The θ-MnNi precipitates with a size of 50–100 nm, mainly formed during aging, were considered as the source of the aging strengthening. In addition, there is a semi-coherent between the plane (111) of the θ-MnNi precipitates and the plane (200) of the α -Cu matrix. The density of θ-MnNi precipitates increases with the increase of the aging time. The hardness, yield strength and ultimate tensile strength of the aged alloy increase from 127 to 366HB, 217 to 788 MPa, and 433 to 842 MPa, respectively, which is attributed to precipitation strengthening.

A novel obtaining method and mesoscopic mechanism of pseudo shear strength parameter evolution of sandstone

Research Square (Research Square) (2022)

Hao Shi Wenlong Chen Lei Song Houquan Zhang

Abstract The pre-peak microstructure evolution of the material is crucial in determining the strength and failure scheme of the material, but is not captured by the existing shear strength parameters models which focus on post-peak stage information. Novel concepts of pseudo cohesion and pseudo internal friction angle that account for both the pre-peak and post-peak stage information were proposed in this study, based on the experimentally observed response of the rock mechanics parameters to an external load (the maximum principal stress). These two parameters were analytically derived as functions of maximum principal strain, with coefficients to be determined (i.e. by applying the Mohr-Coulomb criterion with these parameters to experimental data). The dependence of pseudo cohesion and pseudo internal friction angle on the axial strain and confining pressure were investigated. The evolution of the strength parameters was found to relate to the propagation of micro crack developed in the loading process, as revealed by PFC 2D simulations reproducing experiments. The results show that (1) analytical model characterizing the pseudo cohesion and internal friction angle as the quadratic function of axial strain accurately reflects the mechanical response characteristics of the specimen; (2) before the residual stage, the pseudo cohesion first increases and then decreases with increasing strain, while the pseudo internal friction angle increases continuously; (3) for the sandstone specimens studied, the pseudo cohesion at the peak stress increases by a gradually decreasing rate with increasing confining pressure, while the pseudo internal friction angle at the peak stress decreases by a decreasing rate with the increasing confining pressure; (4) CPM well characterized the mechanical properties of rock under multiple confining pressures, as the total stress-strain curves and failure modes of numerical specimens reproduced the experimental results; (5) the evolution of rock pseudo shear strength parameters is closely related to the external load and the generation, propagation and penetration process of rock cracks. The rock pseudo shear strength parameters are gradually mobilize d with the increasing load, and the propagating of cracks owing to the decrease of mobilizable maximum cohesion and the increase of mobilizable maximum internal friction angle.

Liquid Metal–CO₂ Battery Bridged Intermittent Energy Conversion and O₂ Production in the Martian Atmosphere

ACS Sustainable Chemistry & Engineering (2023)

Hao Shi Zhouyu Fang Muya Cai Minghao Liu Peilin Wang

Oxygen and fuels are requisites for outer space exploration. Herein, we use a liquid Na–Sn cathode and a Ni-based inert anode to convert CO2 into Na–Sn and oxygen in molten Na2CO3–NaCl by electrolysis, aiming to produce oxygen and store solar energy in liquid Na–Sn when the sun shines. In the same Na2CO3–NaCl electrolyte, the liquid Na–Sn serves as a negative electrode coupled with a porous FeNi positive electrode that allows the reduction of CO2 to CO in a primary cell, converting chemical energy stored in Na–Sn into electricity and CO that is a valuable fuel when the sun does not shine. This system has an overall energy efficiency of 51.0% at 100 mA cm–2. Therefore, the molten carbonate electrolysis device equipped with a liquid metal electrode could be applied for producing O2 and storing solar energy in energetic chemicals (e.g., Na–Sn, CO), which could be applied for outer space exploration such as Mars.
