METHOD FOR PRODUCTION OF SAMPLE FOR SHEAR TEST OF LAYER JOINT TO BASE Russian patent published in 2009 - IPC B22D19/08 

FIELD: technological processes.

SUBSTANCE: sample part in the form of ring that represents base is laid on flat surface of lower element of accessory for method implementation. Upper element of accessory having central opening for metal pouring with diametre less than ring internal diametre is installed with its flat surface on ring. Accessory elements and ring create cavity for moulding of sample part that represents layer. Amount of poured metal is selected as sufficient for filling of above mentioned cavity and part of central hole in upper element of accessory. Diametre of opening is selected provided that previous crystallisation of metal is provided in mentioned cavity and puncheon is installed in it. After crystallisation it is possible to deform layer by means of puncheon.

EFFECT: expansion of method technological resources, lower labour intensiveness if sample making, since mechanical processing of sample is excluded.
