<p>[QUOTE=&quot;Oldhoopster, post: 4637552, member: 84179&quot;]I agree that laminations can occur in improperly mixed alloys, but they can also be caused by gas bubbles/voids that are unrelated to poorly mixed allows.&nbsp; In the glass industry, seeds (partially melted raw materials) and blisters (gas bubbles) are common defects.&nbsp; Depending on the root cause, they may be related or form independently.&nbsp; Although I’m not a metallurgist, I would expect similarities between a glass melt and metal melt.</p><p><br /></p><p>You keep saying “I want my questions answered”.&nbsp; I tried to provide answers to your question about the characteristics that led me to conclude that this can’t be an improperly mixed alloy, yet you asked it again.&nbsp;&nbsp; Do you disagree with my explanation that debonding would likely occur along grain boundaries of improperly mixed regions and not cut through differing regions due to ductility/hardness variations?&nbsp; Do you disagree that varying compositional regions in the melt (or partial melt) may have different viscosities and that it would be unlikely that a gas bubble would cut through these regions and not stay in the lower viscosity region?&nbsp;&nbsp; I’m not saying those explanations are correct, but the make a lot of sense to someone who has spent nearly 30 years working in the Glass/Ceramic field.&nbsp; &nbsp;&nbsp; </p><p><br /></p><p>I believe I provided a reasonable explanation based on science and will be waiting for your pictures showing laminations cutting through regions of varying compositions while avoiding the grain boundaries.&nbsp; I hope you find your pics, because try as I might, I can’t think of any material science or chemistry explanations that support this.&nbsp; I know there are some chemists and metallurgists on this site and would be interested in their feedback regarding my comments, and am always willing to listen to alternate theories.&nbsp; That&#039;s how we learn[/QUOTE]</p><p><br /></p>
