Try looking into trace log files
DECLARE @filename VARCHAR(100), @filenum int
SELECT @filename = CAST(value AS VARCHAR(100))
FROM fn_trace_getinfo(DEFAULT)
WHERE property = 2
  AND traceid = 1
  AND value IS NOT NULL
SELECT @filename
SELECT @filename = substring(@filename, 0, charindex('_', @filename)+1) + convert(varchar, (convert(int, substring(left(@filename, len(@filename)-4), charindex('_', @filename)+1, len(@filename)))-4)) + '.trc'
SELECT @filename
SELECT gt.EventClass, 
       te.Name AS EventName,  
       gt.TEXTData, 
       gt.NTUserName, 
       gt.NTDomainName, 
       gt.HostName, 
       gt.ApplicationName, 
       gt.LoginName, 
       gt.SPID, 
       gt.StartTime, 
       gt.EndTime, 
       gt.ObjectName, 
       gt.DatabaseName, 
       gt.FileName 
FROM [fn_trace_gettable](@fileName, DEFAULT) gt 
JOIN sys.trace_events te ON gt.EventClass = te.trace_event_id 
WHERE EventClass = 116 
  AND TEXTData LIKE '%Alter
database%' 
ORDER BY StartTime;
