Summary: This study focuses on the semi-solid deformation behavior of A356 aluminum alloys, including microstructure evolution and constitutive modeling. The research starts with investigating the semi-solid deformation behavior of primary dendritic cast structure, instead of using a feedstock prepared through spheroidization process. The findings show that deformation of solid grains in high strain conditions promotes substructure development and dynamic recrystallization in the semisolid temperature range. The penetration of liquid phase along newly developed boundaries also affects the softening behavior of the material. A phenomenological-physical constitutive equation is developed to predict the semisolid flow stress behavior of the material.

Summary: Understanding the process of tool wear is crucial for ensuring workpiece quality during finishing. This study focuses on the potential use of cryogenic cooling to improve tool life and tribological characteristics when machining the AA2024-T351 alloy. Experiments were conducted under dry, minimal quantity lubrication (MQL), liquid nitrogen (LN2), and carbon dioxide (CO2) conditions. The results showed that cryogenic cooling is beneficial for improving tool life and tribological characteristics.

Summary: In this paper, a finite element method (FEM) based model of broaching Inconel 718 was established to optimize an asymmetrical cutting-edge. The power-law material constitutive model and the friction model were developed through tests and measurements. The simulated and experimental results were compared and found to be consistent, verifying the accuracy of the simulation model. The optimal asymmetrical cutting-edge of broach was obtained through orthogonal test based on the FEM model.

Summary: This study investigates an interesting feature in the thermoelastic interaction in an orthotropic material containing cylindrical cavities. The Finite Element Method is used to analyze a generalized thermoelasticity theory with a relaxation time, considering a thermal conductivity dependent on the temperature of the medium. The results demonstrate how changing thermal conductivity affects all physical values.

Summary: The effects of hydrothermal and cold sealing processes on the scratch and wear resistance of the anodic layer were studied. The sealing processes enhanced the wear and scratch resistance by sealing the surface porosity. A thicker oxide layer on the milled substrate led to greater wear resistance. A cracked mechanically mixed layer was formed on the anodized surfaces at the end of the wear tests.

Summary: Aluminum alloys are widely used in various industries, and their machining characteristics play a crucial role. This article reviews and discusses the machining characteristics of aluminum alloys, including machinability, surface integrity, tool wear and life, material removal rate, and chip morphology. The article also explores ways to improve machinability through cutting parameters, cutting environment, tool geometry, and tool materials. The study focuses on turning, milling, drilling, and grinding as the main types of machining. It concludes that aluminum alloys have lower tool wear and different surface integrity compared to steel alloys, and various factors, such as cutting parameters and tool materials, can affect chip morphology and tool life.

Summary: The study used finite element method and response surface method to conduct experiments on cutting X56 pipeline steel with diamond wire saw, and obtained cutting force prediction models. The results showed that cutting depth played the most crucial role in determining cutting force, while the coefficient of friction had less influence, and cutting speed should be moderate.

Summary: A multi-scale approach is proposed for simulating hot tearing during the DC casting of aluminum alloys, combining macro-scale finite element simulation with meso-scale multi-physics granular model to predict hot tears initiation, growth, and propagation. The approach highlights the impact of variations in casting speed and heat extraction on deformation state, cooling rate, and thermal gradient, which further influence strain rate, grain size, permeability, and feeding coefficient. Hot tearing formation maps developed using this approach demonstrate sensitivity to processing parameters and alloy composition, predicting hot tearing locations for alloys AA5182 and AA3104.
