Use of a Fracture Surface Cleaning Method to Evaluate Elevated Temperature Cracking in Steel

Publikováno v: Journal of Failure Analysis and Prevention. 17:796-801

The nature of cracking during continuous casting of steel strip was investigated. Samples removed from steel strip for fractographic analysis were heavily oxidized, preventing effective evaluation of the fracture surface. In order to remove the oxida

Improved weldability diagram for pulsed laser welded austenitic stainless steels

Autor: J. C. Lippold, Thomas J. Lienert

Publikováno v: Science and Technology of Welding and Joining. 8:1-9

Pulsed Nd:YAG laser welds were produced on 23 different austenitic stainless steel alloys of known composition. The primary solidification mode (PSM) and solidification cracking susceptibility of individual welds on each alloy were identified and cor

Ageing behaviour of commercial aluminium-lithium welds

Autor: J. C. Lippold

Publikováno v: Journal of Materials Science. 30:4155-4160

The post-weld ageing behaviour of two commercial aluminium-lithium alloys, 2090 and 8090, was evaluated. Both a 2319 and 5556 filler material were used for preparing welds in Alloy 2090, while only the 5556 filler material was used with Alloy 8090. W

Development of Chromium-Free Welding Consumables for Stainless Steels

Autor: J C Lippold, G S Frankel

Stainless steel components are often joined by welding when fabricated into structures. Fusion welding of these steels results in the formation of carcinogenic Cr(VI) in the weld fumes as a result of the Cr content of the commonly used filler metals.

Hot Cracking Phenomena in Welds II

Autor: Thomas Böllinghaus, Horst Herold, Carl E. Cross, J C Lippold

Failure of welded components can occur during service as well as during fabrication. Most common, analyses of the resistance of welded components against failure are targeted at crack avoidance. Such evaluations are increasingly carried out by modern

An analytical electron microscope investigation of the phase transformations in a simulated heat-affected zone in alloy 800

Autor: M. J. Cieslak, J. C. Lippold, A. D. Romig

Publikováno v: Metallurgical Transactions A. 19:35-50

The heat-affected zone (HAZ) hot-cracking behavior of Alloy 800 was investigated with hot ductility (Gleeble) testing during a simulated HAZ thermal cycle. Microstructural analyses were performed by optical metallography, fractography, electron micro

The relationship between microstructure and fracture behavior of fully austenitic type 316L weldments at 4.2 K

Autor: M. C. Juhas, J. C. Lippold, E. N. C. Dalder

Publikováno v: Metallurgical Transactions A. 16:1835-1848

Multipass weld deposits produced with a Mn-modified Type 316L filler material exhibited fracture toughness nearly 100 MPa√m less than that of a conventional 316L filler material when tested at 4.2 K. Although fracture in both materials occurred by
