“…This result agrees well with the XRD one and confirms thus the biphasic character of In20 alloy. The magnetic transitions of both phases are different from those reported in the literature [26][27][28]. Those discrepancies might be ascribed to the composition change and/or the preparation conditions.…”

A detailed investigation of structure, critical behaviour and magnetocaloric properties of Ni50Mn30Sn20 (Sn20) and Ni50Mn30In20 (In20) alloys has been investigated by means of Xrays diffraction and magnetic measurements. Ni50Mn30Sn20 alloy shows a cubic austenite 2 1 structure, and undergoes a second order magnetic transition at a Curie temperature of ,1 ( 20) = 333 . However, the Ni50Mn30In20 alloy exhibits a mixture of cubic 2 1 and 2 austenite structures having Curie temperatures of ,2 ( 20) = 285 and * ( 20) = 330 , respectively. The modified Arrott plots, Kouvel-Fisher curves and critical isotherm analysis have been used to estimate the critical exponents (, , and ) around the Curie temperature. For Sn20 alloy, the reliable exponents are consistent with the mean field model, revealing long-range ferromagnetic interactions. Nevertheless, the critical exponents of In20 alloy around 330 K cannot be arranged into any of the universality classes of well-known classical standard models. The maximum entropy change under 5 T of Sn20 (∆ = 2.43 . ) is slightly higher than that of In20 (∆ = 2.05 . ). The experimental results of entropy changes are in good agreement with those calculated using Landau theory.

“…After annealing, the alloy is subjected to a relaxation of the structure, which can slightly modify the site of the atom, causing in the change of the Mn-Mn distance. Finally, another justification for this change is the dependence between the annealing and grain size for annealed alloys observed in micrographs [20][21][22]. Glezer et al [22] investigated the correlation between martensitic transition temperatures and grain size in Fe-Ni-B alloys.…”

Impact of annealing on martensitic transformation of Mn50Ni42.5Sn7.5 shape memory alloy

The impact of annealing on the structural and martensitic transformation of Mn50Ni42.5Sn7.5 (at.%) shape memory alloy was systematically investigated using a scanning electron microscope (SEM), X-ray diffraction (XRD), and differential scanning calorimetry (DSC). According to XRD studies, martensite phase a 14M modulated monoclinic structure was detected, at room temperature, for as-cast and annealed alloys. In addition, it has observed that during annealing, the transition temperatures have increased relative to the cast alloy. Also, a high dependence between the cooling rate and activation energy has detected. The more detailed characterization of martensitic transition and account of thermodynamic parameters were examined after annealing. Response to Reviewers:Dear Sir, At first, I would like to thank the reviewer 1 for the constructive remarks and the interest discussions offer for our paper. The given questions pushed us to make another bibliography and discovered the interesting result deduced from the effect of annealing condition on martensitic transformation in a Mn-Ni-Sn alloy. We have considered all your suggestions, which are corrected in the manuscript as following:Responses for Reviewer 1 Comments Question 1: "English text is generally well written using straightforward expressions. However, there is occasional carelessness noticeable in the manuscript and they are better to be corrected by proof reading of the native English speaker." Response Thank you for your comment. The English language has been improved. Question 2: "Page 3, line 4; As you know, vapor pressure of Mn is very high and arc remelting of pure Mn might be very difficult. What was your plan for recycling Mn and control the composition? Meanwhile, evaporation of Mn and its deposition on the visor of the furnace could be another problem. Please explain in detail how did you perform Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation the melting process?" Response Yes, you are right, we detailed the melting process. The equipment used in this study is the Compact Arc Melter MAM-1 model of the commercial house Edmund Bühler. The precursors used to obtain the Mn50Ni42.5Sn7.5 (at. %) bulk alloy are: a Ni metal filament (purity> 99.98%), metallic manganese sheets (purity> 99.98%) and pieces of metallic Sn in the form of small spheres (purity> 99.99%). An extra 5 wt.% Mn was added to compensate for evaporation losses. Polycrystalline of about 4g were prepared by the melting of the precursors under argon atmosphere in a water-cooled copper crucible. The bulk alloy was melted four times, to ensure the homogeneity of the chemical composition. In our case, the starting elements have a high melting point, such as: Melting point of Ni= 1455C, Mn= 1246C, Sn= 231C. To better ensure the recycling of the Mn and control the composition, the elements were placed increasingly according to their melting temperatures more precisely the Sn and the Mn finally the highest Ni. The bulk alloy was fixed in a quartz tube filled wi...

“…To compensate Mn losses during the process, an excess of some few wt% Mn was added, melting the ingot several times to ensure chemical composition homogeneity [10]. Some of the as-spun ribbons were sealed in quartz tubes and annealed during 10 min at different temperatures namely 1048 K, 1073 K, 1098 K and 1123 K. After annealing they were all quenched in ice water.…”
