Fe-rich Fe-B amorphous metals exhibit approximately collinear magnetic structure. When a certain amount of Fe atoms are replaced with Mn, the magnetic structure of the alloys is found to become non-collinear. We performed electronic structure calculations using the locally selfconsistent multiple scattering (LSMS) method for supercell samples generated by ab initio molecular dynamics simulation...

The ma~tensitic transfol-niation (MT) under tensile dcfol.m:ltion at 77K i n a series of FeNi-Mn alloys was studied. The anlotult of ~na~tensite fos~ned d ~ ~ r i ~ l g the tensile test depends on the applied stress and on the Mn content which determines the mnrtensitic point and the MT start stress. Elongation of the tensile tested samples has a maximum value in the alloys co~ltainilig the 50%...

Aim: The aim of this study was to compile the usage of Co-Cr alloys in fixed prosthodontics (FP) among dental laboratories in Sweden. Methods: From March to October 2015, questionnaires were sent to 542 registered dental laboratories in Sweden. The questionnaires were divided in two parts, one for fixed dental-supported prosthodontics (FDP) and one for fixed implant-supported prosthodontics (FI...

most of the plutonium isotopes are alpha-emitters, a fact which is of decisive importance from a biological point of view. we shall consider their potential danger to life in general, and to human life in particular. in this respect measurement of plutonium concentration in air and soil and vegetable is the object of systematic tests in numerous countries. this plutonium occurs in the fallout f...

background: to determine the role of drugs in fatal overdose, analyses were done on samples obtained from autopsy examination and death and crime scene investigations. the aim of this study was to evaluate the usefulness of toxicology analyses of postmortem biological and non-biological samples belonging to a subject in determining the forensic cause of death. methods: toxicological analysis we...

in this paper, hardness and tensile properties of welded zone of aluminum 1100 alloys by friction stir welding process was investigated and the effects of rotational and traverse speeds of tool on these parameters was studied. also the fracture cross-section of welded samples was investigated. according the results of this paper, the hardness of weld material is higher than base material and is...
