Selective laser melting (SLM) has been applied to manufacture various alloy components with excellent properties, but its further application is restricted by the intrinsic defects. In this work, internal defect distributions in samples of three alloys (316L stainless steel, AlSi10Mg and Inconel 718) were investigated respectively, considering effects geometrical characteristics samples. The de...

Bogie spring performance can be improved by using the exact heat treatment process parameters. The purpose of study is to determine critical transformation temperatures and investigate effect cooling rates on microstructural mechanical properties. precise determination required for particular grade steel important in order optimise heavy-duty compression helical manufacturing. A traditional sys...

Steel Fiber-Reinforced Concrete (SFRC) is an advanced material studied and used in some developed countries the world recent years. The characteristics of this concrete are intensive compression, high tensile tolerance strength, higher repeated loads, long-term durable stability. fibers were to manufacture SFRC because their outstanding characteristics. durability should be improved disadvantag...

The article covers issues related to the development of a new domestic tool alloy steel 7ХНМФБ brand for manufacture wood-cutting saws. It is noted that aforementioned saws were previously made from alloyed steels 9ХФ and 9ХФМ grades, which smelted in Russian Federation (RF), also them Federation. With acquisition independence, these became scarce, question arose developing purpose research det...
