Abstract
Bimetal composites are a group of promising engineering materials with high developing and service potential.Especially in many elds they can be a powerful low cost alternative to metalceramic composites. The mostcommonly encountered type of these composites is steel reinforced aluminium matrix composites which stand outwith high wear and abrasion resistance. Signi cant fabrication processes of metal/metal composites are based onliquid metal techniques. In this study, Al/steel composite specimens were produced by using acuumv assisted solidmould investment casting technique. A7075 wrought aluminium alloy were in ltrated into steel preforms, whichwere produced with 304 stainless steel and H13 hot-work tool steel turnings, in the plaster based solid investmentcasting moulds. Microstructure observations, HV microhardness measurements, scanning electron microscopy andenergy dispersive X-ray spectroscopy analysis were carried out for characterization.DOI:10.12693/APhysPolA.126.1327ACS:P 81.30.Fb, 81.30.t, 81.20.n
