In this work laminar steel materials of W1-7 + AISI 304, W1-7 + AISI 430, 1008 + AISI 304 and 1008 + AISI 430 model compositions were studied. The γ→α transformation temperature range bias and influence of such bias dynamics on the laminar structure stability was studied by the differential scanning calorimetry method. The study results have shown that only in the laminar steel material of W1-7 + AISI 304 model composition the γ→α transformation temperature range bias to the low temperature region and the expansion of austenite field occurred, thus ensuring retention of the laminar structure in the process of material synthesis. Also, the nature of γ→α transformation was analyzed for all four compositions which showed that the observed γ→α transformation for each model composition of laminar steel materials was direct.
