A strength-ductility trade-off usually occurs when grains are refined to increase strength. A
question arises on if there exists a grain size for the best strength-ductility combination, ie …

The interfaces introduced in metals by heterostructural design play crucial roles in
mechanical behaviors. Here the effect of gradient interfaces on mechanical behavior was …

In order to shorten the production process of Cu-Fe alloy and improve the microstructure
homogeneity and properties and properties, Cu-10 wt% Fe alloy billet was prepared by …

The versatility of FSW as a joining technique for ferrous and non-ferrous metals depends on
fine-tuned process parameters. To date, reports of mixed success exist in the literature on …

The effect of bead on plate friction stir welding parameters on the tensile properties of the
70/30 brass joints was investigated using response surface method. The microstructures of …

A gradient-structured Cu sample composed of grain-size gradient surface layer (GSL) and
homogeneous coarse-grained (CG) core was fabricated by surface severe plastic …

The paper presents the microstructural investigation of a friction-welded joint made of 316L
stainless steel with an ultrafine-grained structure obtained by hydrostatic extrusion (HE) …

Fine-grained materials possess great industrial significance as they have exceptional
strength, ductility, and superplastic formability. However, the poor thermal stability of these …

Pure copper and brass alloy with 30% wt Zn were successfully dissimilar joined using
friction stir welding (FSW). The microstructure and mechanical properties of the copper and …

The effect of friction stir welding parameters on the mechanical properties of the α/β brass
plates was investigated. The microstructures of the joints were characterized using optical …
