each indentation was about 15 seconds. Readings of hardness (HV) and distance (mm) were taken for microhardness measurement profile along the weldment, as shown in Figure 2. Figure 2: Hardness test profile . RESULTS AND DISCUSSION . Tensile-shear Properties of spot-welded joint . The tensile shear curve of base metal and RSW as-welded is What is the Correct Test Method for Case Hardened Steel This will give you a hardness/depth profile. Plotting a graph hardness verses depth, you can determine the effective case depth at a specified hardness (possibly say 620 HV (~ 56 HRC equiv) at 0.4 mm depth) and the total case depth where hardness levels off to that of the core. Hope that helps.

Softer metals allow for deeper penetration than harder metals, so the B A value will always be higher on soft metal test subjects than hard metals.

Moreover the value of the peak hardness for a special cooling time can be calculated by inserting a cooling time. The Dren-hardness is calculated according to the following formulas: Martensite hardness HV M HV M = 802 x C + 305. Bainite hardness HV B HV B = 350 x CE* + 101. CE* = C +Si/11 +Mn/8 +Cu/9 +Cr/5 +Ni/17 +Mo/6 +V/3 Resulting hardness: Heat Affected Zone and Weld Metal Properties in Welding of 16mo3 hardness hv spot The as-welded hardness data from welds 1 and 2 had shown that the steel plate values were around 170 HV to 180 HV, weld-metal values were 200 HV to 220 HV, and the peak HAZ hardness was below 240 HV. Multiple PWHTs had little influence on HAZ or steel plate hardness, where peak HAZ values of less than 240 HV were obtained and steel plate 16mo3 hardness hv spot Effect of Binary Oxide Flux on Weld Shape, Mechanical 16mo3 hardness hv spot The conducted experimental values obtained for hardness in fusion zone (FZ) are shown in Table 11.

Hardness profiles of the dissimilar and similar joints are presented in Fig. 4. The base materials of A6N01 and A7N01 had the average hardness values of about 103 and 126 HV, respectively. The hardness of the weld zone was reduced by the heat input during the FSW due to the dissolution of the fine precipitates in the joints.
