Bowl surface laser forming process of stainless steel composite plate

Abstract In this paper, the three-dimensional bowl surface was obtained by reasonably planning the radial heating path by taking the laser as the heat source and the stainless steel composite plate (06Cr19Ni10/1Cr17Mn6Ni5N/06Cr19Ni10) as the research object, and the forming process of the three-dimensional bowl surface was studied. It was found that the target surface bending forming obtained by inside-outside symmetric scanning strategy (Strategy d) had the highest accuracy. The plate deformation increased with the increase of laser power (P), increased then decreased with the increase of heating line length (L), and decreased with the increase of scanning speed (V). Moreover, the deformation was approximately linear with the number of repeated heating (N), with the optimal process conditions of P = 500W, V = 10 mm/s, L = 20 mm, N = 7. A three-dimensional thermodynamic coupling model of a three-layer composite plate was established and verified experimentally.

Ti Content

High boron alloyed stainless steel composite plates with different Ti content by cladding casting and hot forming process were fabricated. The mechanical properties of composite plates were analyzed after solution treatment. The results show that the composite plate has optimal microstructure and properties at 1100°C solution temperature, holding for 4h.The comprehensive properties of the composite plates are improved with the increase of Ti content, but excess Ti content can lower the plasticity. The elongation and the tensile strength of composite plate reaches 29% and 527MPa respectively, the mechanical properties can meet and exceed the supply standard requirements in ASTM A887-89 of U.S. when the reasonable content of Titanium is about 5%.
