Nowadays, wrought zinc-based biodegradable alloys are favored by researchers, due to their excellent mechanical properties and suitable degradation rates. However, there are few research studies on their thermal deformation behavior at present. This study took Zn-1Fe-1Mg and explored its microstructural change, deformation, recrystallization behavior and processing map by means of the thermal simulation experiment, at temperatures ranging from 235 °C to 340 °C and strain rates ranging from 10−2 s−1 to 10 s−1. The constitutive model was constructed using the Arrhenius formula. The results indicated that the evolution of microstructure included the dynamic recrystallization (DRX) of the Zn matrix, the spheroidization of the Mg2Zn11 phase, and breaking of the FeZn13 phase. The subgrains observed within the deformed grain resulted mainly from continuous dynamic recrystallization (CDRX). The precipitated FeZn13 grains overlapped with the precipitated MgZn2 from the matrix, thus forming a spine-like structure at the phase interface. After compression, the alloy possessed a strong basal texture. Affected by the change of Zn twins, textural strength decreased at first and then increased as the deformation temperature rose. There was only a small unstable region in the processing map, indicating that the alloy exhibited good machinability.

In this work, copper (Cu) matrix composite reinforced with titanium carbide (TiC) was fabricated by powder metallurgy (PM) method with the varying TiC content from 0% to 12% by weight in the step of 4%. The required weight percentage of powders was milled in an indigenously developed ball milling setup. Green compacts were made using a computer-controlled hydraulic press (400 kN) and sintered in a muffle furnace at a temperature of 950°C. Scanning electron microscope (SEM) was used to analyze the distribution of TiC particles in Cu matrix in as-sintered conditions. X-ray diffraction (XRD) analysis resulted in the existence of respective phases in the produced composites. The structural characteristics such as stress, strain, dislocation density, and grain size of the milled composites were evaluated. Cold upsetting was conducted for the sintered composites at room temperature to evaluate the axial (σz), hoop (σө), hydrostatic (σm), and effective (σeff) true stresses. These stresses were analyzed against true axial strain (εz). Results showed that the increase in the inclusion of weight percentage of TiC into the Cu matrix increases density, hardness, (σz), (σө), (σm), (σeff), and stress ratio parameters such as (σz/σeff), (σθ/σeff), (σm/σeff), and (σz/σθ) of the composites.

“…[1][2][3] The production of zinc alloy matrix composites with suitable reinforcement agents is an effective approach to address the above issues. [4][5][6] Interpenetrating phase composites (IPCs), [7] which possess an interconnected network structure, can effectively transfer and disperse stress between the matrix and the reinforcement phases, thereby impeding crack propagation and enhancing the mechanical properties of the composites. [8][9][10] Thanks to the favorable wetting between metal components, IPCs with intact interfaces can be easily prepared using simple techniques.…”

High‐performance lightweight composites are developed by integrating metal rubber (MR) into a zinc alloy (ZA8) matrix via squeeze casting. MR, comprising 304 stainless steel wires with diameters of 0.15 mm, forms three‐dimensional network skeletons with volume fractions of 8.8 vol.% (S1), 11.1 vol.% (S2), and 13.4 vol.% (S3), respectively. The preparation parameters of the composites are optimized, and their micro‐hardness is investigated. Special attention is paid to the ultimate compression and shear performance at 25 °C, 150 °C, and 250 °C. The microstructure and failure analysis are performed via SEM. The results reveal a 48.0% increase in micro‐hardness at composite interfaces relative to ZA8. At 25 °C, S2 possesses an ultimate compressive strength (UCS) of 401.4 MPa, which is 33.7% higher than that of ZA8. At 150 °C and 250 °C, S3 exhibits UCS values of 180.3 MPa and 74.3 MPa, exceeding those of ZA8 by 61.7% and 110.5%, respectively. Meanwhile, the ultimate shear strength of composites slightly drops below that of the matrix: the corresponding value of S1 specimen (158.4 MPa) at 250°C is 11.5% below that of ZA8. Therefore, compression and shear failure mechanisms of MR/ZA8 composites are quite intricate, involving SSW separation, necking, and ZA8 fractures.This article is protected by copyright.
