  1. Practical aspects of structural tests of titanium-steel bonds made by explosive cladding and exposed to process thermal loads Robert BAŃSKI Politechnika Opolska xplomet Maria SOZAŃSKA Politechnika Śląska Zygmunt SZULC, Aleksander GAŁKA Zakład Technologii Wysokoenergetycznych „EXPLOMET” Gałka, Szulc, Sp.j. - 1 -

  2. Subjectaboutwhich we will not talking • About cladding elements to process apparatus • About cladding for electrotechnic, electrometallurgy and electrochemistry • About cladding bars, tubes and others… elementów.. - 2 -

  3. Subjectaboutwhich we will not talking • About conductive rails for electrolysers of chlorine • About Electrical Transition Joints (ETJ) STJ – Structural Transition Joints ETJ – Electric Transition Joints • About Structural Transition Joints (STJ) - 3 -

  4. Reactor Tubesheet First we have to make cladding plate : ASME SA-240 304 L + ASME SB 265 Gr.1, and later …. there is a question, is this should be heat treated or not? THIS WHAT WILL BE TALKING ABOUT ?

  5. CONTROL OF SET AND PROCESS Making cladding of Ti Gr.1 + 304 L (6 + 95 mm) Control of explosive’s thickness Measurement of detonation speed in productive set - 5 -

  6. And we back to the question, if cladding plate Ti Gr.1 + 304L should be heat treated or not? From cladding plate in sizes: (6+95) x 3150 x 3150 mm was taken test plate and test samples.

  14. TEST’S Conclusions 1. HEAT TREATMENT MAKES DECREASING HARDENING IN BOTH MATERIALS AND IN BOND ZONE. 2. ACCUMULATION OF CARBON IN DIFFUSSION LAYER CAN MAKE INCREASING OF ITS FRAGILE WHAT MEANS ALSO DECREASING OF BOND STRENGHT Negative … 3. ECXALATION OF CHROMIUM CARBIDE ON THE BORDER OF GRAINS IN AUSTENITIC STAINLESS STEEL CAN MAKE DECREASING ITS RESISTANCE FOR INTERGRANULAR CORROSION Negative … BECAUSE OF OBSERVED DECREASNG OF STRENGTH OF BOND ZONE AND BECASUE OF UNPROFITABLE PHENOMENONS DESCRIBED IN POINT 2 AND 3 IN CONCLUSIONS, HEAT TRAETMENT OF CLADS TITANIUM – AUSTENITIC STAINLESS STEEL SEEMS TO BE INEXPEDIENT.
