Effect of Zn Addition on the Microstructure and Mechanical

Nov 25, 2020 · The microstructure was varied to a large degree by various heat treatments at high temperatures above 400°C, and the relationship between the microstructure and mechanical properties was clarified. Effect of Zn Concentration on the Microstructure and Jun 08, 2018 · The mechanical properties of the alloy are determined by its microstructure. Because of the irregular morphology and discontinuous distribution along the grain boundaries, the AlMgZn phase [ -MgZn 2 and -Mg 32 (Al, Zn) 49 ] inhibits crack initiation and accelerates crack propagation, which results in a decrease in the ductility but enhances the strength of the Al-Mg-Si-Zn alloy in the as-cast

Effect of proeutectoid carbide on heredity in

Heredity in the microstructure and mechanical properties of hot-rolled spring steel wire 60Si2MnA during heat treatment process was investigated comprehensively. Evolution of microstructure and mechanical properties of Abstract The effects of superheat temperature, content of modifier (P) and T6 heat treatment on the microstructure and mechanical properties of the Al50Si alloy have been investigated systematically by scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). The results indicate that the primary Si exhibits a plate-like morphology, with average size decreasing with Investigation of Microstructure and Mechanical Properties The comparison is done on the basis of microstructure and mechanical properties of the welded joint of TIG and MIG welding on aluminium alloy 6062. It was observed that MIG welding has better tensile strength, hardness, impact strength and microstructure

Dependence of microstructure, mechanical properties, and inter-granular corrosion behavior of Al-5.1Mg-3.0Zn-0.15Cu alloys with high temperature pre-treatment Shengli Hou, Microstructure and Mechanical Properties Evolution of the The effect of cold rolling on the microstructure and mechanical properties of an Al- and C-containing CoCrFeNiMn-type high-entropy alloy was reported. The alloy with a chemical composition (at %) of (20-23) Co, Cr, Fe, and Ni; 8.82 Mn; 3.37 Al; and 0.69 C was produced by self-propagating high-temper Microstructure and Wear Properties of TiCVC Reinforced The composition and amount of flux evidently affect the microstructure and properties of the coatings. Good crack resistance and higher hardness of the harfacing layer could be obtained, while the amounts of graphite, FeTi and FeV were controlled within a range of 810%, 1518% and 812% respectively.

Microstructure and mechanical properties of bamboo in

In this work, the microstructure and mechanical properties of Phyllostachis dulcis bamboo are studied to help produce a model for the mechanical properties of bamboo. Specifically, a linear relationship is established between the density of bamboo samples, which is Microstructure of the Synthetic Cast Iron Carburized with The cast iron melting process can be based on metallic charge with pig iron or on steel scrap exclusively (i.e. synthetic cast iron). The analysis of the synthetic cast iron microstructure was presented and compared to micros of the cast iron produced on the base of pig iron. The analysis consisted of size and shape of the graphite precipitations and the metal matrix structure, too. On the Role of Copper and Cooling Rates on the the mechanical properties of Al-Si cast alloys. The cool- ing rate determines the coarseness of the microstructure including the Secondary Dendrite Arm Spacing, SDAS, which is often used as measure of the coarseness of the microstructure, the fraction, size and distribution of in- termetallic phases and the segregation profiles of solute

Processing, Microstructures and Mechanical Properties of

A second-generation Ni-based superalloy has been directionally solidified by using a Bridgman method, and the key processing steps have been investigated with a focus on their effects on microstructure evolution and mechanical properties. The as-grown microstructure is of a typical dendrite structure with microscopic elemental segregation during solidification.

The effects of Ca and Mn on the microstructure, texture Oct 02, 2020 · Currently, however the application of MgZn binary alloy has been limited by some poor properties, such as the large crystallization temperature interval and the hot cracking tendency [5,6]. Therefore, it is necessary to alloy the MgZn alloy with additional elements in order to improve the microstructure and mechanical properties.
