Heating rate. Laser energy within hundredths of a second to thousandths of a second or less time, the parts near the surface heating at the temperature quickly rose to above 1000 ℃, heated to high temperature, holding time is extremely short, so the heating condition with conventional heating methods have a great deal of difference. The formation of austenite for eutectoid steel, conventional heating rate conditions, the steel is heated to above AC1. Formation of austenite is achieved through nucleation and growth process, the basic process includes: 1) austenite nuclei formed at the interface of ferrite and cementite; 2) the growth of austenite; ) the continuation of the residual cementite dissolution;) austenite homogenization process. Sub-eutectoid steel and over eutectoid steel of austenite formation process and common analysis of steel is essentially similar to, but the increase in excess of the phase transformation and dissolution characteristics have. green laser pointer  ensures that the voice being transmitted is clear and with high quality.
The cooling rate in Figure 2 the isothermal cooling transformation C curve (TTT diagram) the merger of C curve and continuous cooling transformation (CCT diagram) schematic. Which abc curve for the isothermal transformation of austenite to the pearl breaks and Bayesian start line, Ms is the martensite transformation start line a 'b' c 'is the austenite to pearl size bainite isothermal transformation End of line. Abc line above the left and Ms line for supercooled austenite region (breeding area), austenite above the A1 temperature rapidly cooled to below the Ms temperature, rather than meet with the abc line is not transformed into pearlite or bainite, can only be transformed into martensite. Under continuous cooling conditions, due to the undercooling.Ease of coating and uniform thickness. The weight of the transmitting terminal (including the batteries of green laser pointer ) and the receiving terminal is 60g.Non-interface growth of grain, grain refinement, otherwise the interface growth of columnar grains, grain refinement. Where N0 is the number of cores per unit volume of heterogeneous, △ of TN for the critical nucleation undercooling △ Tc is the front of the interface undercooling, the value (map VC0 / A) 1/2, C0 is the alloy content, A is a constant. Is clearly whether grain refinement and the number of nucleation agent, the nucleation undercooling and solidification rate, the alloy concentration dependent, rather than just depending on the cooling rate. It can be seen from the above equation, the laser rapidly solidified, there are many conditions not conducive to grain refinement. First, the high cooling rate is often accompanied by a high temperature gradient, high temperature gradient to promote the formation of the interface growth of columnar crystals. The computer will install the software of green laser pointer automatically.
