Hardness of cubic solid solutions
We demonstrate that a hardening rule exists in cubic solid solutions with various combinations of ionic, covalent and metallic bonding. It is revealed that the hardening stress ∆τFcg is determined by three factors: shear modulus G, the volume fraction of solute atoms fv, and the size misfit degree δb. A simple hardening correlation in KCl-KBr solid-solution is proposed as ∆τFcg = 0.27 G. It is ...
متن کاملPremium class testing devices for medical technology – Our expertise for safe medical technology!
tled Personalised Care, to be presented at the Medica Education Conference 2013 (21 November), Sir John will re-buff any cynicism over personalised medicine ever having a role in healthcare. He will outline just how genome analysis detects an individual’s genetic predisposition for certain diseases and how better assessment of their prognosis will play a greater role as personalised medicine ta...
متن کاملTesting of Macroscopic Hardness by Acoustic Response
ČERNÝ MICHAL, ŠUSTR MICHAL, DOSTÁL PETR. 2016. Testing of Macroscopic Hardness by Acoustic Response. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(3): 751–758. Static measurement of macroscopic hardness (hereina er macrohardness) of metal materials by using indentation testing is accompanied by deformation in the vicinity of the indenter. Its indenting in a material...
متن کاملOn the Characterization of Wang’s Class of Premium Principles
A premium principle is an economic decison rule used by the insurer in order to determine the amount of the net premium for each risk in his portfolio. In this paper we investigate the problem of determining the premium principle to be used. First, we discuss some desirable properties of a premium principle. We prove that the only premium principles that possess these properties belong to a cla...
متن کاملLow-Load Vickers Microindentation Hardness Testing
ADVANCED MATERIALS & PROCESSES • APRIL 2012 I n 1925 in the UK, Smith and Sandland developed an indentation test that used a squarebased pyramidal-shaped indenter made of diamond[1]. The test was developed because the Brinell test (introduced in 1900), which (until recently) used a round hardened steel ball indenter, could not test steels harder than ~450 HB (~48 HRC). They chose this shape wit...
