As I have long recommended this technology for testing thermal fatigue stress relaxation for die casting dies, I was a bit unhappy as I could not find anyone who owned and used this device from Bonal Technologies or others, and where it could be tried.<\/p>\n

According to Bonal Technologies, by applying this method of annealing to machined parts, the results were improved by 50%, in the case of weldments by 69%. Overall, scrap was reduced by 50%. At the same time, this method saves 62 to 95% of annealing costs, and 50% to 95% of time. In today’s age of energy savings, it is something to consider, at least try it out. Bonal offers Meta-Lax equipment for $337.55\/month.<\/p>\n

Is it really that perfect? I don’t know, it needs to be verified and tested. Until recently, I thought that such a device was not available in our country. I was wrong.<\/p>\n

Not too long ago, a client called me asking if I knew of anyone who would be cheaper than the existing suppliers. I was very surprised, although I suspected that someone had it, but I did not know the details.<\/p>\n

So, these are 3 contacts for companies that offer vibration annealing for roughly 0.5 CZK\/kg. At current prices for classic annealing without a protective atmosphere or in a vacuum, it is many times less.<\/p>\n

Comparison of the effect of thermal and vibrational annealing on stress relaxation (https:\/\/www.stressreliefengr.com\/about.html<\/a>)<\/em><\/p>\n

And how to determine the effect of vibration annealing on the removal of internal stress?<\/p>\n

More, for example, on this link:<\/p>\n

https:\/\/www.researchgate.net\/publication\/42795493_Determination_of_Residual_Stresses_by_X-ray_Diffraction\/link\/5df37c61a6fdcc28371d8f8d\/download<\/a><\/p>\n

https:\/\/www.sae.org\/standards\/content\/j784a_197108\/<\/a><\/p>\n

X-ray diffraction will answer our question quite quickly and accurately. The principle is described in the SAE J784a standard. All you have to do is take a sample of the die or part where the load or damage has occurred due to thermal fatigue and X-ray the sample. Then let it relax by the vibration method and analyse the X-ray again. The internal stress \u00a0difference will be what we are looking for.<\/p>\n
