Mo-Si-B Alloy Development
Alloys consisting of the phases α-Mo (Mo solid solution), Mo3Si, and Mo5SiB2 (“T2”) were fabricated by ingot and powder metallurgy. A novel powder-metallurgical processing technique was developed which allows the fabrication of silicide alloys with a continuous α-Mo matrix. In these alloys the relatively ductile and tough α-Mo matrix acts as a “binder” for brittle silicide particles. An alloy p...
متن کاملMicrostructure Characterization and Wear-Resistant Properties Evaluation of an Intermetallic Composite in Ni–Mo–Si System
Intermetallic compounds have been studied for their potential application as structural wear materials or coatings on engineering steels. In the present work, a newly designed intermetallic composite in a Ni-Mo-Si system was fabricated by arc-melting process with commercially pure metal powders as starting materials. The chemical composition of this intermetallic composite is 45Ni-40Mo-15Si (at...
متن کاملEffect OF SI and AL on the Microstructure, Mechanical Properties and Machinability of 65CU-35ZN Brass
Relations between the microstructure, mechanical properties and machinability of as-cast 65Cu-35Zn brass with various amounts of Al from 0 to 4.72 and Si from 0 to 3.62 wt% were investigated. Both Si and Al initially enhanced the UTS and toughness of the brass samples, which led to improvement in machinability due to a reduction in the main cutting force. A duplex brass with random oriented α p...
متن کاملEffects of Zr Additive on Microstructure, Mechanical Properties, and Fractography of Al-Si Alloy
The effects of Zr additive on the microstructure, mechanical properties, and fracture behavior of Al-Si alloy were systematically investigated. The additive of Zr obviously reduced the size of Si particles and changed its morphology. Grain size refinement was promoted by the reaction between Al and Zr forming Al3Zr and ZrSi2 compounds. Compared to a Zr-free alloy, the additive enhanced the tens...
متن کاملInfluence of Rolling Temperature on Microstructure and Mechanical Properties of Cryorolled Al-Mg-Si Alloy
An effect of rolling temperature on the mechanical properties and microstructural evolution of an Al-Mg-Si alloy was studied. The material was rolled up to a true strain of ∼0.7 at three different temperatures viz; room temperature, liquid propanol and liquid nitrogen. The liquid nitrogen rolled sample exhibited superior properties with a yield and tensile strength of 332 MPa and 364 MPa, respe...
