Metal parts produced by Additive Manufacturing, and in particular Laser Powder Bed Fusion (LPBF), suffer from residual stresses due to high thermal gradients causing cyclic expansion contraction of the alloy. This work deals with determination stress rapidly solidified AlSi10Mg samples using two non-destructive techniques: Raman spectroscopy, rapid, unconventional but applicable AlSi alloys, XR...

In hypoeutectic Mg-Al-based alloys, Mg17Al12 forms in the last stages of solidification by a eutectic reaction that is usually fully or partially divorced. Here we investigate nucleation, growth and morphology Mg17Al12-containing multicomponent Mg-9Al-0.7Zn-0.2Mn alloy. Under all conditions studied, formed an interconnected skeleton 3D orientation domains spanned multiple α-Mg grains, indicatin...

The literature often mentions that cast irons appear eutectic by thermal analysis are hypereutectic if one refers to the equilibrium phase diagram. This is a source of ambiguity and confusion. experimental results on has previously shown taking into account solidification path during primary precipitation graphite makes it possible differentiate slightly from very irons. approach applied here i...

Abstract We present a fundamentally different approach to process the bimodal Ti-based alloy (Ti-Nb-Fe-Co-Al) by semi-solid sintering stemmed from hypoeutectic reaction, aiming at achieving ultrafine eutectic structure, β-Ti and micron-sized dispersed phase with strengthening effect. As expected, microstructure of processed Ti-Nb-Fe-Co-Al contains local structure (β-Ti TiFe), residual equiaxed ...

Hot-pressed aluminium and silicon coated boron steel is used in the car industry where high tensile strength is of great importance, such as in the safety cage of a car where deformation has to be kept to a minimum in case of a collision. After hot-pressing the AlSi-boron steel shows excellent properties with high tensile strength, minimal spring back and also shows good protection against corr...

Abstract The hypoeutectic aluminum alloy AlSi5Cu2Mg is used for the production of high-strength cylinder head castings. unique its specific low permitted Ti content (0.03 wt% max), which makes it impossible to refine grain structure this using standard Al–Ti–B refiners. chemical composition specified by supplier company. aim paper find a suitable alloying element that would improve selected pro...
