Abstract
The analysis of influence of double hardening and false cementation, direction of a fibre and the form of a cut of samples on impact strength chisel steels (0,19% C, 0,35-0,65% Cr, 0,6- 0,95% Mn, 0,35-0,75% Ni, 0,2-0,3% Mo) Open Society MZ «Izhstal» manufactures, Open Society MZ «Electrostal», Open Society «OEMK», Open Society MZ «Krasnyi Oktyabr» is made. It is established that implementing false cementation instead of double heat hardening can reduce the values of impact strength - by 4-8 %, change of a longitudinal fibre on cross-section - from 10 to 65 %, change of an U-shaped cut on V-shaped - from 16 to 50 %. It is recommended for improvement of quality entrance control of finished сhisel steels to define impact strength on samples of Sharpi with a longitudinal and cross-section arrangement of a fibre.

Abstract
The results of laboratory studies of acoustic emission under uniaxial compression samples stonecasting based materials synthetic mineral fusion are presented. It is established that the destruction of the samples is preceded by acoustic activity is caused by structural changes in the material. Fracture is preceded by the accumulation of inter stresses in the material. The character of acoustic emission and the load, which maintains the material depends on the amount of amorphous component in its structure.
