Contribution

The paper provides a critical commentary on previous responses about the cap-cast technique, emphasizing the need for detailed procedural information for proper evaluation.

Findings

Clarification of previous responses on glassy alloy production

Identification of missing details in the cap-cast technique

Highlighting unresolved questions about the method's necessity

Abstract

Yokoyama and Inoue gabe their replies to eight questions raised by the present author with respect to their paper on "Production of Zr55Cu30Ni5Al10 glassy alloy rod of 30mm in diameter by a cap-cast technique" in 2007. Yokoyama and Inoue stressed in their reply that there were no inadequeate descriptions in their paper, except for the catalog name of a TEM machine, which was a typographical error. It is still unclear why a cap-cast technique is needed to produce glassy alloy rods up to 30mm in diameter. Lack of essential information regarding the cap-cast technique leads us no valuable assessment of a new technique. Further questions arose.
