Caption: Temperature of the glass transition (T g), onset of the first (T x1) and the second (T x2) crystallization peak, extension of the supercooled liquid region (DT x = T x1 - T g) and crystallization enthalpies (DH x1, DH x2) for the Zr58.5Ti8.2Cu14.2Ni11.4Al7.7 melt-spun ribbon and ball-milled powder

You are provided with a table from a material science paper. Here are JSON templates for two types of numeric cells: "Other" and "Glass_Compound_Amount":
{"value": "xx", "type": "Other"}
{"value": "xx", "type": "Glass_Compound_Amount", "constituent": "xx", "unit": "xx", "material": "xx"}

Please describe all numeric cells in the above table following the JSON templates (proceeding by row in a left-right, top-down direction). For each cell, output one JSON description per line. For any unanswerable attributes in the templates, set their value to the placeholder "xx".
