A new kind of Mg-2Zn-0.6Ca (wt％) alloy was fabricated by casting and hot extrusion as a high-ductility structural material.The extruded alloy exhibits a superior elongation of ～ 30％,yield strength of 130 MPa and ultimate tensile strength of 280 MPa along the extrusion direction at room temperature.Microstructure,texture and tensile properties of the extruded alloy were investigated in details.The remarkable improvement of ductility is ascribed to the weakened basal texture,refined grains and a small number of second phase in the alloy.

A systematic study on the wettability and interactions between superalloy melts with various Re contents and Al2O3-based ceramic moulds was presented in this paper.It was found that the increase of Re content inhibited the interfacial reactions to some ex
The microstructure and fracture toughness of weld metal under Ti-free and Ti-containing different fluxes were investigated in this study.It was found that the trace element Ti of flux in submerged arc welding produced significant influence on the fracture
Optimization of grain boundary engineering (GBE) process is explored in a Fe-20Cr-19Mn-2Mo-0.82 N high-nitrogen and nickel-free austenitic stainless steel,and its intergranular corrosion (IGC) property after GBE treatment is experimentally evaluated.The p
The inclination angle of the flake particle has a significant impact on the in-plane thermal conductivity of composites.The graphite flake/Al composites (50 vol％) with different inclination angles were fabricated via flake powder metallurgy,and the result
High-strength,corrosion-resistant,and lightweight Al-Mg alloys perform an important function in harsh coastal service environments.Corrosion resistance is generally inversely correlated with strength;hence,it is difficult to simultaneously optimize both.I
Ni-Mo-P coatings are obtained at the surface of ceramic substrate by electroless deposition using palladium as a surface catalyst.The influence of catalyst activation conditions on coatings\' properties was assessed by structural,morphological,electrica
Mg and its alloys are the lightest structural metals available and are extremely attractive for applications as lightweight components,particularly in the automobile,electronic,and aerospace industries.The global market for wrought Mg alloys has steadily
The microstructure,mechanical properties and corrosion behavior of Mg-2Zn-0.6Zr alloy under the as-cast and asextruded conditions were investigated.Microstructure analysis indicated the remarkable grain refinement by extrusion,as well as notable reduction
Machining,especially dry machining of titanium alloys,has been one of the most significant challenges for carbide cutting tools.In this study,aluminum-rich AlTiN coating,as well as TiA1SiN nanocomposite coating,were successfully employed for dry milling o
An M-coated Mg-8 mass％ Li alloy rectangular bar was fabricated by hot extrusion,and then,it was hot-rolled into a thin sheet.The Al coating was uniform in thickness and had good bonding with the substrate during all the processing.This Alcoated Mg-Li allo
