ABSTRACT:
Carpenter Technology Corporation has within the past two years purchased an RSLTM Rising Step Load Bend Testing System. This state-of-the-art machine and test method (ASTM F1624-05) allows KISCC values to be determined on fracture mechanics bend samples per ASTM E399/E1290 in far less time than the standard double cantilever beam test approach (incorporating procedures from NACE TM0177), which has been proven to be somewhat unreliable with high-strength corrosion-resistant grades. In addition, KIEHE values are easily obtained with this apparatus, as it allows testing to be run at various controlled applied potentials. This talk will give a general overview of the test apparatus and methodology, and will compare recent results of stress corrosion cracking (KISCC ) and hydrogen embrittlement (KIEHE) testing of 300M, Custom 465Æ stainless, Carpenter FerriumÆ S53 (manufactured and sold under license from Questek Innovations LLC), and Carpenter AerMetÆ 100 alloys. The data represent samples held at potentials ranging from open circuit, where the sample is freely corroding in 3.5% NaCl test solution, to -1.10VSCE (saturated calomel electrode), simulating cathodic charging while being galvanically coupled to zinc.
BIO:
Dave Wert holds a B.S. in Metallurgy from Penn State University, having graduated in 1981. He has been employed in the Research and Development Lab at Carpenter Technology Corporation for the past 28 years, spending the entire time in the area of Alloy Development. He started his career working on Tool and Alloy Steels, and holds 2 patents on hot work die steels. Dave then focused on high strength/high toughness steels, and is the inventor/co-inventor on 4 patents in this area, including AerMet 100, AerMet 310, and Pyrowear 675 Stainless alloys. Returning to the tool steel area, Dave worked in the area of P/M High Speed Steels, and holds a patent for Carpenter Maxamet Alloy, a H.S.S. capable of hardness of HRC 70. For the past 8 years, he has been working in the area of Stainless Steels. Dave is currently listed as the co-inventor for 2 patent applications in this area, which include a modification to improve fatigue-resistance of Carpenter Custom 465 Stainless Alloy, and a new high strength stainless strip alloy. Also, in the past year and a half, along with his alloy development/customer service function, Dave has been devoting some of his time to getting Carpenter's new RSL (Rising Step Load) test machine installed and running.
