The effect of destabilization heat treatment on the microstructure, hardness, fracture toughness and abrasive wear resistance of high chromium hardfacing was investigated. The results from the study...
In present days composite materials are the indispensable part of many branches. They make a foray into the branch of agricultural production, where they are getting to intensive development of system...
Tool graded materials (TGM) incorporate gradual transitions in their microstructure and composition with distance. The gradients provide means to favourably engineer their thermo mechanical properties...
Metallic glasses (also known as metallic amorphous alloys) are newcomers to the group of amorphous materials. First, metallic glass (Au75Si25) was made by Duwez in 1960 and developed with the use of t...
Purpose: of this paper is investigation of dynamic impacts on cutting edge during machining of locally hardened steel. Alteration of hardness on a single work piece is a source of impact on tool, whic...
Quality is a challenge that must be taken up by producers and other organisations. A formal requirement of quality are among others ISO 9000 standards, specific branch requirements e.g. ISO/TS 16949 (...
Purpose: The purpose of this article is to present results of examining the hardness of the high density polyethylene with method of the cone. Design/methodology/approach: In the article a method of...
The densification behaviour of aluminium, iron and alumina powders under cold isostatic pressing (CIP)are examined. For this purpose, a unit which can withstand up to 650 MPa pressure was designed and...
Purpose: The purpose of the present study is to produce low ally PM steel without any addition and with addition of ferro-boron addition by conventional PM manufacturing route at the different sinteri...
Purpose: Burnishing is a chip less machining process in which a rotating roller or ball is pressed against metal piece. It is a cold working process and involves plastic deformation under cold working...
Findings: The different heat treatment kinds employed contributed to the improvement of mechanical properties of the alloy with the slight reduction of its plastic properties. Research limitations/im...
Purpose: of this paper was to examine of the secondary hardness effect after tempering of the developed complex hot-work tool steel 47CrMoWVTiCeZr16-26-8 in relation to standard hot-work tool steel X4...
Purpose: Double layer Cr+TiN thin films were coated on SS-420 substratum to achieve a corrosion resistive system.Design/methodology/approach: Ion coating technique was employed for deposition of TiN o...
期刊信息 篇名 Hardness Variations during Aging Process of Deformed W-Ni-Fe Ternary Alloys with High Nickel to Iron Ratios 语种 中文 撰写或编译 撰写 作者 Li Ronghua,Huang Jihua,Yin Sheng,Zhao Jun 第一作者单位 University of Sci...
The experiments were conducted on alloy AlSi12, following a factor design 23 for 3 independent variables. Mixtures composed of NaNO3, Na2B4O7, and Mg were used for alloy treatment. The amount of a red...
