A study on galling initiation in friction coupling stretch

Apr 15, 2015 · Hot-dip galvanized dual-phase AHSS DP590 steel having tensile strength of 590 MPa was selected as the material for the sheet/strip specimens. DC53 cold work tool steel was selected as die (forming tool) material, which was heat treated to HRC 6062 A study on variable friction model in sheet metal forming Jan 01, 2016 · The hard DC53 tool was machined into circular disc specimen with diameter of 38 mm, which was subsequently heat treated to hardness HRC 61 and then carefully polished to achieve surface roughness of Ra 0.04-0.05 m. The dimensional information and the fabricated pin/disc were as shown in Fig. 1 (b) and Fig. 1 (c), respectively.

Changing Steel Guitar Strings Taylor Guitars

There are as many variations on the process of changing steel strings as there are players, and not all methods are equally effective.
