Effect on Explosive Cladding of TITAN 12/SS 304 L Plates under Multiple Conditions (Design Matrix)

Abstract

Joining of dissimilar metals has always attracted attention of researchers because of their wider applications in aerospace, defense and naval applications. Explosive cladding is one of the non-conventional diffusion bonding techniques, which offers strong and metallurgical bonds in dissimilar metal combinations. Attempts were made to explosively clad titanium (ASTM grade 1)stainless steel (SS 304L grade) plates using granular nitroglycerine explosive (detonation velocity 2800 m/s). The flyer (titanium) and the parent (SS) plates were of 3.5 mm and 3.0 mm thickness, respectively. The experiments were conducted by adopting a 3 parameter-2 level design matrix and by varying the e/m ratio (1.0 and 1.75), preset angle α (3° and 8°), and stand-off distance (5 mm and 10 mm). All the experiments were open air explosions. The micro structural changes, interfacial wavy configuratio ns and modifications, and the effects of the parameters on the strength of the bond are discussed. Models have been developed correlating the parameters and the strength of the bonds.

The Effect of Heat Treatment on the Microstructure and Properties of Explosively Welded Titanium-Steel Plates

“…Some types of coatings require special welding or bonding methods, such as explosive bonding (Ref [1][2][3]. This is a highly efficient technique used to join a wide variety of similar and/or dissimilar metals such as steel and titanium (Ref 4,5).…”

Research on microstructure and mechanical properties of explosively welded stainless steel/commercially pure Ti plate

“…Samples for microstructures observations were cut from bimetal in a parallel direction relative to joining direction. To reveal the titanium microstructures, samples were ground, polished using 0.6 mm Al 2 O 3 powder and etched in lactic and nitric acid with hydrofluoric acid and in distilled water solution according to P. Tamilchelvan investigations [3]. According to R. Kacar research, stainless steel microstructures were revealed using the nital and following oxalic acid solutions in distilled water [10].…”

“…The problem of the surface protection is one of the most important subjects in the production of modern engineering structures, due to increasing demands in the area of efficiency, strength, reliability and fatigue life of required applications. Often surface protection is realized by coatings, but due to different chemical composition and structure of the connected materials, sometimes joining process is impossible to carry out by conventional welding or bonding methods [1][2][3]. This problem can be solved by using an explosive welding method which is one of the most effective technical engineering processes among joining methods because is used to join a wide variety of similar or different metals like steel and titanium [4].…”

Investigation of high temperature deformation process of aluminium based alloys using response surface methodology

“…In the field of design of experiments (DOE), response surface methodology (RSM) is a collection of mathematical and statistical techniques that are useful for the modeling and analysis of problems in which a response of interest is influenced by several variables and the objective is to optimize this response [5,6]. Central composite design (CCD) experiments using RSM proved to be an optimal tool for the optimization of medium parameters.…”

Hence, the number of combination of setting in which experiments to be conducted is 2 5 ¼ 32 for aluminium alloys. The treatments are listed below and responses are recorded for aluminium alloys with two replicates as shown below.…”
