The cement industry is facing the challenge of a lack supplementary cementitious materials substituting clinker. This applies primarily to granulated blast furnace slag, most commonly used as main component cements, due changes in metallurgical industry, and siliceous fly ash abandonment fossil fuels world. A potential new common cements may be calcined marls, which are available large quantiti...

The paper presents the model of operator’s specialist traveling crane for qualitative needs of studies on human work place. The crane accepted for analysis supports the metallurgical process of rolling sheets.

The paper considers the role and tasks of transport industry in economic complex Russia sanctions imposed. analysis predicted changes international logistics allowed staging recommendations for amendments to basic policy documents growth. Also, substantiates need adjust certain points development projects within Eurasian Economic Union (EEU). authors analyzed meaning railway transport, which is...

This case study involves two continuously cast steel crankshaft failures. Three parties performed their own failure analyses: (1) the engine manufacturer responsible for component design, specification, and application; (2) the steel supplier and forging supplier responsible for making the steel, forging the shape, and preliminary heat treatment; and (3) a supplier that provided induction harde...

One of the main sources non-ferrous and precious metals is sulfide ores. This paper presents a review existing literature on electrochemical properties some most common industrial sulfides, such as pentlandite, chalcopyrite, sphalerite, galena, pyrrhotite, pyrite, etc. The study results surface redox transformations minerals, galvanic effect, cathodic oxygen reduction reaction sulfides are pres...

The joined influence of fortifying metal matrix composites with separate and numerous particle reinforcing agents like hybrid are utilized greatly in the manufacturing industry. This is attributed to enriched mechanical wears characteristics such as strength, impact wear resistance. In present study, a series research undertakings were carried out. paper directs technologists scientists towards...

Influence of homogenization on mechanical properties of Al-1Mn-1Mg alloy prepared by different melttreatments was discussed and mechanism of metallurgical defects on ingots’ mechanical properties was analyzed. It was found that metallurgical defects, such as the inclusions and gas holes, cannot be removed from the original ingots by homogenization; the average increasement of tensile strength o...

The composition dependence of the emission intensities was investigated in Cu-Ni as well as Ni-Zn binary alloy samples when a low-pressure argon laser-induced plasma was employed as the excitation source. The calibration curve in the Cu-Ni alloy system gave a linear relationship, implying that the selective evaporation of Cu or Ni atoms was caused less in those alloys having several chemical co...
